SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 406,733, dated J' uly 9, 1889.

Application fried Epine 18559. saai No. 305,913., (remodel.)

To aZZ whom it may concern.:

Be it known that I, CALVIN M. I-IERvEv, a citizen of the United States, residing at Fulton, in the county of Hempstead and State of Arkansas, have invented certain new and'useful Improvements in Sulky-Plows; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to sulky-plows; and it consists in the novel construction and arrangement of its parts hereinafter described in this specification and set out in the accompanying claims.

In the accompanying drawings, Figure l is a side elevation of my sulky-plow, with the left-hand wheel and the axle cut away at the line a: 0o, Fig: 2. Fig. 2 is a rear view of my Vinvention. Figs. 3, 4, 5, 6, and 7 are detail The object of my invention is to bring about in sulkyplows durability, simplicity, and cheapnessdurability, in that it is all made of durable metal, and is not liable to rot, wear, shrink, crack, or break; simplicity, in that it is composed of so few pieces and pieces soV constructed that it may be put together by very few bolts and nuts, the axle, the plowtached wheels b c.

beam, the seat, and the centerfwheel sleeve all being firmly secured in place by means of the clamping-block and two U -bolts and nuts; cheapness, in that because of its few pieces it can be manufactured and sold at a price below most sulky-plows before invented and put upon the market, and at a price that brings it withinthe reach of small planters.

I do not claim anything for the wheels nor lifting apparatus. My claims are on the castiron combination-block and its combinations.

My invention is described as follows:

To an ordinary axle a, made square, are at- Tlle right-hand wheel c is so set on its end of the axle that its lower periphery stands in, the object of which is well known to planters. The right-hand end (Z, to lift the plow out of the ground when 1desired.

I do not claim anything new for the lifting device. I do not confine myself to the particular one here illustrated, but in the manufacture of my plow shall use any lifting device which I find suits my purposes better.

A To the plow-beam c is attached a turningplow or such other plowpointes may be proper from time to time to use. In front of said plow-point f runs a cutting-wheel g, borne in a brace h, the upper and forward end of which isv rigidly secured to the pin l,whiehis pivoted in the half-sleeve Z, secured to the other half-sleeve Z of the cast-iron combination brace-block 7c by means of the U-bolt m, secured in place by nuts; or I may dispense .with the half-sleeve Z and have U-bolt m to clamp the said pin fi tightly on the half-sleeve Z, in which case the brace h wouldbepivoted `block there is an extension 5, leaving the pei# forations j and 9 9. From the lower face of said. extension 5 extend two flanges 6 6,1eaving a groove 7, in which the axle a exactly fits 'and is secured, and on the face'of the block is a half-sleeve Z', its inner surface being tiush with the face of the perforationj.

In putting the plow together the axle is fitted Vin the groove 7. The U-bolt 8 is then put astride the said axle up through the perforations 9 and block k, and then through the perforated Aend of the seat-spring fn and secured by nuts. The beam e is then placed across the axle and in slot 3. The half-sleeve of the axle is provided with a lifting device Z is then put on the half-sleeve Z ,and the U- bolt m is then put asti-ide the said half-sleeve Z, through the perforations 10 in the block 7c and corresponding perforations in the beam e, and secured by nuts. Thus it will be seen that by means of this cast-iron combination IOO brace-block la the axle a, the Ybeam e, the springseat'n, and the half-sleeve Zare all rigidly and securely'. held in place by means of said block to U-bolts and their nuts.

Having described my invention,WhatI'clairn as new, and desire to secure by Letters Patent, 1s-

l. Thecoinbination of the brace-block Zt, having the groove 3, iiange 4, extension 5, having the groove 7 -and perforationsj and 9, and the center piece having the perforations l() and the half-sleeve Z, with axle cv, fitting in said groove 7, VSeatSpring n, fitting on the upper face of said extension, U-bolt 8 and .nuts binding the Whole together, beam e, itting in slot 3, half-sleeve Z, fitting on half- Sleeve Z', and U-bolt m and nuts, binding the Whole together, substantially as shown and described.
